Akunabo bonke abathandi bokulima beyazi ukuba i-sapropel yintoni. Okwangoku, isetyenziswa ngokubanzi kwimveliso yesityalo, ukunyanga kwezilwanyana kunye nakwiyeza. Makhe sibone ukuba yintoni into enomdla njengepropropel, apho ikhankanywe khona kwaye yiziphi iimpawu zesicelo sayo kwezolimo.
Sapropel kunye neendawo zayo
I-Sapropel yidiphozithi eqokelela kwiindawo eziphantsi kwamanzi amanzi iminyaka emininzi. Kubantu abafakela i-sapropel kuthiwa kuthiwa udaka - eli gama liyazi wonke umntu. Iqukethe iincinci ezincinci kakhulu zehlabathi kunye nezilwanyana kunye nokudibaniswa kweemaminerali ezahlukeneyo. Ezi zilandelayo ziquka i-nitrogen, i-phosphorus kunye ne-potassium, isinyithi kunye ne-manganese, ubhedu kunye ne-boron, nabanye abaninzi. Iimbotyi ezantsi zizityebi kwiithamini ze-B kwaye ziqulethe ezininzi i-carotenoids kunye ne-enzymes. Ngelinye igama, i-sludge exhaphakileyo yinto nje yiphozithi yezinto ezincedo ezichaphazela kakuhle umhlaba kunye neenkcubeko ezikhulayo. Ingasetyenziselwa ukuba ifakwe kwimo engokwemvelo njengesichumiso esilula kunomyezo.
Ukuveliswa kwezichumisi, i-sapropel igxothwa kwizinga lemveliso, emva koko lomekile kwaye liphathwe ngokufanelekileyo. Imveliso yinto eyomileyo ngesimo se powder, apho ungasifika khona umhlaba okanye udibanise kumhlaba.
I-Sapropel ekhishwe kwiindawo ezahlukileyo ezihlukeneyo zihluke ngokuphawulekayo ekubunjweni, okuxhomekeke ngokuthe ngqo ekubunjweni komhlaba wendawo. Kukho i-carbonate, organic, ferrous and siliceous iintlobo ze-sapropel. Inokumiselwa ukuhlaziywa kwamachiza. Ichaphazela ngqo indlela i-sapropel yale ntlobo isetyenziselwa ukukhula kwezityalo. Makhe sijonge indlela yokusebenzisa i-sapropel njengesichumisi.
Ukusebenzisa i-sapropel njengesichumisi
Ngokungafani ne-peat, isichumiso esekelwe kwi-sapropel iqulethe izinto ezininzi zetrogen, i-carbohydrates kunye nama-amino acids. Oku kwenza ukuba i-sapropel ibe yindlela ebonakalayo, kodwa kungekho rhoqo. Ukuba i-peat isetyenziselwa kakhulu ukucebisa umhlaba nge-humus, izichumiso ezisuka kwi-silt zinomphumo olandelayo:
- uhlalutyo lomhlaba;
- i-aeration eyongeziweyo;
- Ukuphucula inkqubo yeengcambu zezityalo;
- ukwandiswa kwesivuno;
- Ukuphuculwa kwezakhiwo zomhlaba ezifana nokubamba nokugcinwa kwamanzi;
- ukwanda kwimixholo ye-humus emhlabeni;
- ukuhlanjululwa kwiimfuyo nezifo.
Olunye uhlobo olungenakuphikiswa lwe-sapropel njengesichumisi kukungqinelana nokusingqongileyo. Ngokungafani nezichumisi zamaminerali, zikhuselekile kubantu nakwizilwanyana. Kwaye xa kuthelekiswa nomgquba, apho kukho izilwanyana ezinobungozi kunye nembewu yokhula, umxholo we-silt kule ndawo uhlukile.
Ngokubhekiselele ekusebenziseni kwe-sapropel, isetyenziselwa ukucwiliswa komhlaba ngokuthe ngqo kunye nokuququzelelwa komgquba . Kwimeko yokuqala, i-sapropel ifakwe kwisixa semali engama-35-40 ngetoni nganye kwi-haha yomhlaba (i-nafta) okanye i-65-70 iitoni (imifuno kunye nezityalo ezihlukahlukeneyo).
Kufuneka kuqatshelwe ukuba ukusetyenziswa kwe-sapropel ngokubhetele kukuhle kumhlaba onesihlabathi kunye nomhlaba onesihlabathi wemiphunga kunye neentlobo ezimuncu. Kule meko, umphumo ongcono kakhulu ufunyanwa ngumlinganiselo wokuqala wenhlabathi.
